NAME

CURLOPT_TIMEVALUE_LARGE - time value for conditional

SYNOPSIS

#include <curl/curl.h>

CURLcode curl_easy_setopt(CURL *handle, CURLOPT_TIMEVALUE_LARGE,
curl_off_t val);

DESCRIPTION

Pass a curl_off_t val as parameter. This should be the time counted as seconds since 1 Jan 1970, and the time is used in a condition as specified with CURLOPT_TIMECONDITION(3) .

The difference between this option and CURLOPT_TIMEVALUE(3) is the type of the argument. On systems where 'long' is only 32 bits wide, this option has to be used to set dates beyond the year 2038.

DEFAULT

0
